I bought four of these "sorbers" and also two extra top sections to add a little height. The panels fold together easily and packs up against the wall when not in use. They are easy handle and the finish is a sober grey, they actually double up as a neutral background for video recording too. Putting three panels in a half circle around the microphone and artist and the fourth panel as a roof on top of the others, the room acoustics are effectively reduced on the recordings, and it also reduces some of the noise that would otherwise reach my neighbours. The recordings get dry, free from room acoustics and i am free to add any reverb or echo later in the mix. This is an excellent alternative to glueing lots of acoustic material to the walls and the ceiling. Setting these sorbers up is a matter of a four minutes and they drastically improve the sound of the recordings.
